There is no such thing as 3 months for a plant to flower and fruit with that short period of time. Your tree will need sunshine, fertilizer, water, and checking for bugs. That takes A LOT OF TIME - not 3 months. A couple of years maybe.
Cuttings and seedlings are out of the question.
Even if you buy already a fruiting tree, it's going to take 6 to 8 months for the fruit to mature. Taking care of a plant is pretty expensive.
Would you consider just buying fresh fruits from the store then?
